| <p>Several files for JVM configuration are included in Cassandra. The <code class="docutils literal notranslate"><span class="pre">jvm-server.options</span></code> file, and corresponding files <code class="docutils literal notranslate"><span class="pre">jvm8-server.options</span></code> and <code class="docutils literal notranslate"><span class="pre">jvm11-server.options</span></code> are the main file for settings that affect the operation of the Cassandra JVM on cluster nodes. The file includes startup parameters, general JVM settings such as garbage collection, and heap settings. The <code class="docutils literal notranslate"><span class="pre">jvm-clients.options</span></code> and corresponding <code class="docutils literal notranslate"><span class="pre">jvm8-clients.options</span></code> and <code class="docutils literal notranslate"><span class="pre">jvm11-clients.options</span></code> files can be used to configure JVM settings for clients like <code class="docutils literal notranslate"><span class="pre">nodetool</span></code> and the <code class="docutils literal notranslate"><span class="pre">sstable</span></code> tools.</p> |
| <p>See each file for examples of settings.</p> |
| <div class="admonition note"> |
| <p class="admonition-title">Note</p> |
| <p>The <code class="docutils literal notranslate"><span class="pre">jvm-*</span></code> files replace the <a class="reference internal" href="cass_env_sh_file.html#cassandra-envsh"><span class="std std-ref">cassandra-env.sh file</span></a> file used in Cassandra versions prior to Cassandra 3.0. The <code class="docutils literal notranslate"><span class="pre">cassandra-env.sh</span></code> bash script file is still useful if JVM settings must be dynamically calculated based on system settings. The <code class="docutils literal notranslate"><span class="pre">jvm-*</span></code> files only store static JVM settings.</p> |
